    Study Notes

    Intracranial Pressure and Alzheimer's Disease

    • Stable increased intracranial pressure (ICP) is characteristic of certain neurological conditions, requiring careful monitoring.

    Prion Disease

    • A prion disease linked with dementia is known for its neurodegenerative effects and presents unique pathophysiological challenges.

    Amyloid Plaques

    • The predominant component of amyloid plaques in Alzheimer’s Disease is β-amyloid peptide, which accumulates in the brains of affected individuals.

    Neurofibrillary Tangles

    • Neurofibrillary tangles in Alzheimer’s Disease are primarily made up of hyperphosphorylated tau protein, a key feature in the disease's pathology.

    Institutionalization Phase

    • Certain behaviors or conditions do not align with the institutionalization phase of Alzheimer's Disease, which is typically marked by severe cognitive decline and loss of daily living skills.

    Parkinsonism and Alzheimer's Disease

    • Approximately 20-50% of Alzheimer's Disease cases may present with overt parkinsonism, reflecting the overlapping pathologies of these neurodegenerative diseases.

    Brain Regions Affected

    • The primary motor cortex is not commonly affected by cerebral atrophy and ventricular enlargement associated with Alzheimer's Disease, which tends to impact other regions like the hippocampus and cortex.

    Cholinergic Transmission

    • A notable deficit in central cholinergic transmission occurs in Alzheimer’s Disease due to the loss of cholinergic neurons, particularly in the basal forebrain.

    Locus Coeruleus and Neurotransmitters

    • The synthesis of norepinephrine decreases as a result of cell loss in the locus coeruleus in individuals with Alzheimer’s Disease, impacting alertness and cognition.

    Treatment Side Effects

    • Certain treatments for Alzheimer’s Disease are known for considerable side effects, necessitating careful patient management.

    NMDA Antagonist Memantine

    • A common side effect of NMDA antagonist memantine is not typically associated with significant cardiovascular issues, distinguishing it from other medications.

    γ-Secretase Activity

    • The activity of γ-secretase in Alzheimer's Disease can be disrupted by various factors including genetic mutations and environmental influences.

    Amyloid Plaque Formation

    • Strategies aimed at disrupting or preventing the formation of amyloid plaques in Alzheimer’s Disease are considered difficult to develop, posing challenges for researchers.

    Immunization with β-amyloid

    • The main outcome of immunization with β-amyloid is related to the reduction of amyloid burden in the brain, potentially altering disease progression.

    Nootropics

    • A feature of nootropics (cognitive enhancers) is their ability to improve cognitive function through various mechanisms, although not all claims are supported by evidence.

    Clinical Failures

    • The clinical failure of tau aggregate inhibitors and neurotransmitter modulators suggests that the complexities of Alzheimer’s Disease require more comprehensive treatment strategies.
